While fooling around with my fiance, I accidentally tore his foreskin with my engagement ring. He bled a lot but wouldn't go to hospital. Will he be okay or could I have done him some permanent damage?

This sort of accident happens very commonly. In fact, it's not a good idea to go in for love play while wearing a sharp ring. That advice applies to both women and men. Your partner will probably be fine but he ought to have this injury checked out by his GP. And please, no sex until he has fully healed.
